Record Class TypedKey<T>

java.lang.Object
java.lang.Record
cloud.opencode.base.rules.key.TypedKey<T>
Type Parameters:
T - the value type | 值类型
Record Components:
name - the key name | 键名称
type - the value type | 值类型
public record TypedKey<T>(String name, Class<T> type) extends Record
Typed Key - Type-Safe Key for Fact and Variable Access 类型化键 - 用于事实和变量访问的类型安全键

Provides compile-time type safety when accessing values from FactStore and RuleContext, eliminating the need for manual casting.

在从 FactStore 和 RuleContext 访问值时提供编译时类型安全， 消除手动转换的需要。

Usage Examples | 使用示例:

TypedKey<String> CUSTOMER_TYPE = TypedKey.of("customerType", String.class);
TypedKey<Double> ORDER_AMOUNT = TypedKey.of("orderAmount", Double.class);

// Type-safe access
context.put(CUSTOMER_TYPE, "VIP");
String type = context.get(CUSTOMER_TYPE);

    • toString

      public String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()

      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.
